how to manage _id field when using POCO with mongodb c# driver

Question

If I want to read and write mongo data with a POCO

public class Thingy
{
     public string Foo {get;set;}
}
...
coll.Insert(new Thing(Foo = \"hello\"));
         


        

Answer 1

Add a property as follows:

public BsonObjectId Id { get; set; }

The MongoDB driver automatically converts Id to _id during serialization\deserializtion.
